A 40 SR doesn't have a back plate as it's a rear induction engine. Do you mean the 40FSR??? I have both but I'd have to check.

RE: back plates
 

You are right it's a 40FSR.
Thanks

RE: back plates
 

Just checked. A 40 FX will not fit a 40FSR. I may have a spare backplate. I'll look in my box of sapre parts.

Thanks[:o]

RE: back plates
 

Has anyone tried to see if the backplate off a 40FP or 35FP will fit the 40 FSR?

I have both, and could check, if there is any interest. I might try it just for my own curiousity.

RE: back plates
 

They won't work.

Thanks for taking the time to check

I have a backplate for a 40-46SF part#25407000
I am not sure if it will fit your engine or not though.
Maybe someone can chime in

RE: back plates
 

just curious .... will a glow engine run without a back plate?

RE: back plates
 

Two stroke no, Four stroke yes.

A four stroke may run without a backplate, but the con rod would be in peril if you did.

RE: back plates
 

...yes and not only the conrod. The Bigend from the conrod can snap out to the backside of the engine and for sure not only the conrod gets destroyed if this happens. Don't try this at home...

Kind Regards,

Nope, won't fit.
Just checked, I got one. Send me a couple bucks for shipping and it's yours. PM me your address and I'll get it out tomorrow. I'm going out of town Friday so get me your address qjickly.

RE: back plates
 

I'm leaving Friday so if you want the back plate let me know ASAP

RE: back plates
 

Yep, didn't mean to suggest that it would be a good idea to do so.

Do you still want that back plate?? It's packaged up and ready to send.
